fabrication facilities in Cold Spring, Minnesota. Awarded LEED gold certification from the U.S. Green Building Council (USGBC) in 2008, the building has 31-percent less square footage than the former building. Coldspring is a member of the Natural Stone Council (NSC) and President and COO, John Mattke, is past-chairman of the NSC's Committee on Sustainability, which has partnered with the University of Tennessee's Center for Clean Products in 2007 to provide research and define the environmental footprint of stone. For the center’s Natural Stone Industry Environmental Benchmarking Study, data was captured from both quarry and processing operations to characterize the environmental profile of the natural stone industry. Findings spurred continuing research on key issues ranging from water reclamation and consumption efficiency, identification of market niches and alternative uses for scrap stone, to the potential establishment of a corporate environmental policy for quarry closure; thereby compelling the development of industry best practices, life-cycle datasets and material fact sheets.
